Hi Hannes,

This commit creates the freedom for boards to do nothing with the whole IRQ stuff on x86 during u-boot.
This is especially important on older systems which have many legacy irq and no ACPI support within BIOS, they get in trouble if, for example, u-boot does mask all the interrupts on a PIC.
Can you elaborate more on what specific issues are here? x86 interrupt was designed to keep backward compatible and I don't think current codes will break anything.
